Although HIV testing, care and treatment coverage have been improving in Sub-Saharan Africa, significant numbers of HIV-positive individuals still drop out of HIV care at various stages along the care continuum. One approach to improving HIV and AIDS services along this continuum is to integrate them with other health services. A literature review shows that there are many initiatives working on integrating services and many approaches being tried. Most of the results are positive: HIV service uptake and health outcomes improve, as do health outcomes related to the other health services into which HIV services are integrated. The evidence on cost-effectiveness is more limited, but most studies find that integration is at least not less cost-effective.
